Name: Date: Class Period: Metric Unit Conversion Part A. The International System of Units (abbreviated as ​
SI​
) is a system closely related to the Metric System. It’s the most used system of measurement used by scientist throughout the world and it will be the system that we use in our classroom as well. Because of this it’s important that we be familiar with the different units of measurement we will be using and are able to convert units as needed. Some important units we will be working with are: Meter​
​
(m)​
– Unit of length Gram (g)​
– Unit of mass Liter (L)​
‐ Unit of volume Part B. What type of measurements are the following units measuring? Choices are: Length, temperature, mass, time, and volume 1​
. km _______________ 2​
. mg _______________ 3​
. m _______________ 4​
. kg _______________ 5​
. ml _______________ 6​
. cm _______________ 7​
. L ________________ 8​
. ms _____________ 3​
9​

____________ Part C. Now that we have a better understanding about units, let's start converting them. Converting SI units will come naturally to you once you get the hang of it and it's much simpler than trying to convert English units. The 'Stairs' method is commonly used to convert units because it's easy to use. This method allows the user to covert units by counting and moving the decimal left or right. Complete this illustration and become familiar with it: There are five steps to follow when using this method but remember, base units are found in the middle of the stairs in the 'unit' box. When in doubt, look for the prefix. If there's not one then start in the middle. Let's try this method on the following problem: 5 Hectometers = ___________ Kilometers 1. Locate the known unit prefix on the stairs.​
(Hecto) 2. Locate the unit prefix you want to convert to. ​
(Kilo) 3. Count the number of times you would put your foot down on a new step if you moved on the stairs from step 1 to step 2. ​
(1 step) 4. Did you go left or right on the stairs? ​
(Left) 5. Move the decimal (.) the number of steps you took in step 3 and in the direction you took in step 4 and you will have converted from your original unit to your new unit. ​
